I have had a system for many years on 2 travel trailers and a 5th wheel. I selected the brand because the sensors were the smallest and lightest. I ran them on standard rubber valve stems and never had a problem. I decided to add them to my dually since it had no sensors. That was a mistake. I had them cause a problem with the inner tires on both sides deflating the tires. The TPMS supplier said that they were successful on most valve extensions. That was not the case as I tried different extensions. Apparently the added weight of the sensor creates a problem with the long stem on the inner tires. I have since had metal stems installed but am now reluctant to run the sensors on them also do to their length.
